Hello, everyone.
This is Enta.

Here is an introduction to a medication that hardens from the inside to prevent internal pressure from building up.
The chemical I've been using a lot for waterproofing this time isHaisel OH-9X
By the way,OH = Oh-haThat's what they say, lol
To explain how this works: as shown in the photo above, it adheres to soil particles and turns rubbery.
It hardens when it comes into contact with water, so water is essential.
I made an injection pipe to inject this.

This is it.
However, after a lot of trial and error, we are now using an improved version of this injection pipe.
As it is injected deep into the soil, it gradually reacts with the moisture, hardens, and becomes rubber-like.
Since it can also be pressed in, it can be injected over a fairly wide area.
As you inject this into several spots, the water level will gradually decrease.
Please inject the solution into the areas where as much soil as possible remains.
If it's just the water part, it takes a while to stop.
The trick is to make sure it doesn't run for more than 60 seconds, which will help it set.
Once you try it, you'll find it's surprisingly easy to stop.

You can also adjust the gel setting time by mixing it with water first, so please experiment with that.
See you later.
